1.1 本试验方法涵盖了岩土工程应用中土工膜的加速破坏性试验方法。 1.2 本试验适用于现场制作的粗布增强或非增强土工膜。 1.3 本试验方法适用于使用化学熔合剂或主体化学熔合剂作为接缝机制的现场接缝工艺。 1.4 根据现场特定合同计划、规范和CQC/CQA文件，对接缝验收标准做出后续决定。 1.5 以国际单位制或英寸磅单位表示的数值应单独视为标准。每个系统中规定的值不一定是完全相等的；因此，为了确保符合标准，每个系统应独立使用，并且两个系统的值不得组合。 1.6 危险品-- 在本试验方法中使用烘箱可能会加速试样和用于粘合试样的溶剂产生烟雾。 1.7 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.8 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ===意义和用途====== 4.1 重要性-- 在各种应用中，越来越多地使用土工膜作为阻挡材料来限制流体从一个位置迁移到另一个位置，以及在连接土工膜片时使用的各种类型的接缝方法，产生了对标准化测试的需求，通过这些测试可以比较各种接缝，并可以评估接缝系统的质量。此测试方法旨在满足这种需求。 4.2 使用-- 加速接缝试验提供了有关现场接缝状态的信息。通过该测试方法获得的数据应与现场特定的合同计划、规范和CQC/CQA文件一起使用。该测试方法可用于规范测试和比较目的，但不一定测量接缝可能获得的极限强度。

1.1 This test method covers an accelerated, destructive test method for geomembranes in a geotechnical application. 1.2 This test is applicable to field-fabricated geomembranes that are scrim reinforced or nonreinforced. 1.3 This test method is applicable for field seaming processes that use a chemical fusion agent or bodied chemical fusion agent as the seaming mechanism. 1.4 Subsequent decisions as to seam acceptance criteria are made according to the site-specific contract plans, specification, and CQC/CQA documents. 1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.6 Hazardous Materials— The use of the oven in this test method may accelerate fume production from the test specimen and solvent(s) used to bond them. 1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 Significance— The increased use of geomembranes as barrier materials to restrict fluid migration from one location to another in various applications, and the various types of seaming methods used in joining geomembrane sheets, has created a need to standardize tests by which the various seams can be compared and the quality of the seam systems can be evaluated. This test method is intended to meet such a need. 4.2 Use— Accelerated seam test provides information as to the status of the field seam. Data obtained by this test method should be used with site-specific contract plans, specification, and CQC/CQA documents. This test method is useful for specification testing and for comparative purposes, but does not necessarily measure the ultimate strength that the seam may acquire.
